Quartz sand as filter material application, quartz sand is combined with the filter container, used to intercept suspended particles in the water, such as particles of impurities, so as to play a role in filtering. Mainly can be divided into the following categories:

1, ordinary quartz sand filter material: mainly used in sewage treatment, with three to five years is no problem, as long as to prevent loss of quartz, polluted not tight, because the sewage treatment, sludge can be aerobic or anaerobic respiration in the sewage, degradation.

2, refined quartz sand filter material: used in water treatment, in the sand filter, usually 2 to 3 years to be replaced, pollution is commonly, after the pollutants covered quartz sand is not renewed to good filtering effect the and can only be replaced. Quartz sand filter material through the Iso9001-2000 quality system certification. In the neutral and pH value in the range of acidic water is very stable, but there is slightly soluble in alkaline water, chemical water treatment in the incremental 2mg/L does not exceed SiO2.

Quartz sand filter material for woven bag packaging, each bag weight 50KG, or ton bag. Quartz sand filter with supporting materials and other materials should not be stacked together. Quartz sand filter material and other filter material should not be with other toxic and harmful substances and pollution items piled up together. Can not cover storage, to prevent pollution of stored dust, general warranty period of ten years.
